===Early history of UHF channel 21 in central Alabama===
The [[UHF]] channel 21 allocation in [[Central Alabama]] was originally allocated to [[Gadsden, Alabama|Gadsden]]. The first television station in the region to occupy the allocation was WTVS, which operated during the 1950s as an affiliate of the [[DuMont Television Network]], and was one of the earliest UHF television stations in the United States.

However, it was never able to gain a viewership foothold against the region's other stations; its owners ceased the operations of WTVS in 1957, as it had suffered from severely limited viewership due to the lack of television sets in Central Alabama that were capable of receiving stations on the UHF band (electronics manufacturers were not required to incorporate built-in UHF tuners into television sets until the passage of the [[All-Channel Receiver Act]] by the [[Federal Communications Commission]] (FCC) in 1961, although such tuners would not be included on all newer sets until 1964).<ref>{{cite web|title=Appendix 10: A Trail of Bleached Bones|url=https://dumonthistory.com/a10.html|website=DuMont History}}</ref>
